Range

Found across Europe (9 countries) and North America (United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Cheetah

猎豹是地球上奔跑最快的陆地动物，在非洲和伊朗草原上短距离冲刺速度可达112千米/小时。体型纤细，胸深腿长，具有标志性的黑色泪纹。与其他大型猫科动物不同，猎豹以吱鸣声和咕噜声交流。由于栖息地碎片化和与更大型捕食者的竞争，猎豹被列为易危，野外仅剩约7,000只。

common whorl snail

<em>Vertigo pygmaea</em>, commonly known as the common whorl snail, is a minute land snail in the family Vertiginidae, listed as Near Threatened on the IUCN Red List, reflecting documented population declines attributable to habitat loss, agricultural intensification, and wetland drainage across its European and North American range. The species occurs across much of Europe and parts of the United States, typically inhabiting short-sward calcareous grasslands, chalk and limestone downlands, damp meadows, and the bases of grassy slopes where the vegetation structure is open and low-growing. <em>Vertigo pygmaea</em> is among the smallest terrestrial mollusks, with a shell typically measuring only 1.5–2 mm in height — a feature shared by all members of the genus Vertigo. Despite its tiny size, the shell is complex, with multiple internal tooth-like lamellae visible within the aperture that are used in species identification. The species typically feeds on decaying plant material, algae, and fungi associated with soil and leaf litter microhabitats. It requires specific microhabitat conditions including moderate soil moisture and an abundance of calcium for shell formation. Biological traits including average lifespan, precise shell dimensions, and mass remain poorly documented in standardized databases. Conservation efforts for <em>Vertigo pygmaea</em> typically focus on maintaining and restoring calcareous grassland habitats through appropriate grazing management regimes.
